White Pizza: Caramelized Onions, Mushrooms + Rosemary Potatoes with Garlic Cream Sauce

You thought you knew pizza. You didn’t know pizza.

Not until now, my friends. And now? We’re getting real friendly (ow ow!) with the ‘za!

Like, it’s kind of hot & crazy.

White Pizza: Caramelized Onions, Mushrooms + Rosemary Potatoes with Garlic Cream Sauce | SheEats.caSpeaking of crazy, how about this weather, amiright? It’s certainly not hot. It’s the dead of Winter and my legs have never been whiter. Or more hairy.

….I’m not the only one who “forgets” to shave her gams mid-March, am I?

Snow is blanketing the East coast, rain is pummeling the West (though the flowers are loving it!) and the sun seems to have abandoned all hope of wooing vine-ready cherry tomatoes and fresh strawberries.

I know I have.

And assuming by the length of my leg hair, John has abandoned all hope of gettin’ it on with a lady.

….Yikes. Someone should really do something about that.

So yeah. Winter. We’re right in the thick of it. But that’s not the only crazy thing going on up in here, up in here. You may or may not have noticed I haven’t posted in about 3 months.

Again, yikes.

I’ve missed you.

I’ve not only been hiding with my tail in front of the fire place, I’ve also been balls deep in creating my cookbook – the deadline for which is fast approaching. Between that, running my design business, lunching and brunching with wonderful friends, starring in major Hollywood movies (okay, okay, I’m background acting), getting my photos on the covers of books, working out with my personal trainer and eating all the cake, shit’s all KINDS of crazy.

But hey, no one ever said the life of a Renaissance woman was easy. Or cheap.

But I am.

Life, though? Not so much.

White Pizza: Caramelized Onions, Mushrooms + Rosemary Potatoes with Garlic Cream Sauce | SheEats.ca
What’s all this rambling got to do with pizza? Nothing. Except this: Pizza. Is. Life.

So let’s talk about this pie!

It was inspired by my milky white legs & the extra padding (on my ass) that Winter brings – not to mention the limited produce available right now. There are no tomatoes for a red base, no peaches to mingle with prosciutto, and no fresh arugula to garnish the top.

And you know what? With a pizza like this one – White Pizza: Caramelized Onions, Mushrooms + Rosemary Potatoes with Garlic Cream Sauce – that’s okay. Because Winter gives us a whole other box of toys to play with. And I wanted to create a pizza that paid homage to those very things.

Or at least to the beauty that is this season.

While it may be cold and blustery and rainy, carbs and cheese make everything okay.

So here’s to the quiet moments only a fresh blanket of snow brings.

Here’s to being snuggled up next to your cuddle-bug in front of a roaring fire.

Here’s to bottles of red wine and the extra pant size that comes from them.

Here’s to Winter.

And to the light at the end of the tunnel.

Because even though it’s mid-March and the weather is kicking our asses, the days are getting longer. The flowers are peaking out of planters. And I can just about almost taste new Spring potatoes.

Here’s to the crazy. Both inside and outside all of us.

Buen Provecho!

White Pizza: Caramelized Onions, Mushrooms + Rosemary Potatoes with Garlic Cream Sauce




Yield 4 servings


For the pizza:

  • 1 batch of homemade pizza dough
  • 1 large sweet onion, peeled & sliced (approx 1 1/2 C sliced onion)
  • 1 Lb button mushrooms, sliced
  • 1 white potato, thinly sliced (a mandolin works very well for this!)
  • 1 Tbsp fresh rosemary, stemmed & finely chopped
  • Extra virgin olive oil
  • Coarse sea salt + fresh cracked black pepper
  • 1 8oz ball (or bocconcini balls) fresh mozzarella, drained

To serve: Dried chili flakes, chili oil, truffle oil and/or shaved Parmesan

For the cream sauce:

  • 1 head garlic
  • 1 Tbsp butter, unsalted
  • 3/4 Tbsp white flour
  • 1 C cream
  • 1 tsp coarse sea salt


  1. Make the pizza dough. As it rises, pre-heat the oven to 400 degrees F. Place a 6" piece of tinfoil inside an oven proof bowl. Cut the top off the head of garlic to expose just the tips of the cloves within. Lightly drizzle with olive oil and sprinkle with coarse sea salt. Wrap up the garlic inside the tinfoil to ensure the heat gets trapped inside. Place in the oven and roast 40 - 45 minutes - the garlic should be oozy and lovely when poked with a fork. Remove from the oven and set aside until it's time to make your cream sauce.
  2. As the dough rises and the garlic roasts, you can prepare the pizza toppings. Heat 1 Tbsp of extra virgin olive oil in a large saute pan over medium-low heat. When hot but not smoking, toss in the sliced onion and a generous pinch of coarse sea salt. Stirring regularly, saute for 40 - 45 minutes or until the onions become soft and have caramelized. Remove from the pan and set aside.
  3. Toss the mushrooms and another good pinch of salt into the pan and if need be, an extra splash of olive oil. Increase the heat to medium and return the pan to the heating element. Stirring often, allow the mushrooms to cook through and just begin to get some colour on them, about 20 - 25 minutes. Remove from the pan and set aside to cool.
  4. At this point, you should be able to touch the garlic without burning yourself. Squeeze the pulp into a bowl and reserve for the garlic cream sauce. Discard the casings.
  5. Finally, in a bowl toss the thinly sliced potato with the rosemary and a Tsp of olive oil. Set aside.
  6. When the dough has about 10 minutes left to rise, preheat your oven to 500 degrees F and place 2 baking sheets in the oven as it heats.
  7. At this time you can make the garlic cream sauce. Place butter in a saucepan over medium heat. When it begins to sizzle, combine the flour and cook for 1 minute, stirring constantly. Remove from the heat and whisk in the cream, coarse sea salt and roasted garlic. Return to the heat and whisk constantly until the mixture thickens, approx 3-4 minutes. Set aside.
  8. Once the dough is rolled out and transferred to the prepared baking sheets as described in this post, lightly brush the top of the crust with 1 Tsp of olive oil. This will help it brown. Top with the cream sauce, rosemary potatoes, mushrooms and then onions. Place in the oven and bake for 12-15 minutes or until the crust is golden. Remove from the oven, top with the fresh mozzarella cheese and place back in the oven for 5 minutes. Let cool 5 minutes before slicing and serving with your choice of garnishes. Eat!

A great big giant sloppy thank you to Elle at G Ceramic & Co for the incredible plates and bowls featured in this post. As one of her very good friends, I can tell you she’s kind of rad. Almost as rad as the pizza…. Almost.

    We have pizza night weekly. A good bit of what I can in the summer is specifically for pizza, so I always have red sauce on hand, but I also use pizza night to clean out the fridge. This past week, I grabbed a jar of pepper jelly and used that with goat cheese. I liked it. Everyone else thought it was ‘interesting’. I found I liked it even better cold and leftover – it was like having pepper jelly and cheese on crackers ready to go!

    This pizza looks incredible. And your photos are out of this world. Would it be sad to admit I’ve never had a white sauce pizza? Probably die to my family’s lack of adventure but I’ll have to remedy that. And this looks like just the pizza to do it with. Yum!

    Hahaha you crack me up! My legs also stay “warm” for winter with an extra layer 😉 this pizza looks amazing though. I’ve become a big fan of white pizza recently but still haven’t made one at home. Will give this a try this weekend.

    My weekend NEEDS this pizza! Seriously!
    I wondered why you hadn’t posted in a while. I guess cookbook manuscript deadlines are tighter than I thought. Yikes! Good luck! You can do it!
    And spring has definitely sprung over here in Montreal, but I bet winter will randomly rear its ugly head to remind us it’s not done. That happens to us every year. Sunshine, warmth, and then boom! Snow storm! Sigh…

      haha, I know, it’s been a while Janice. The deadline is tight, but I also have 2 other full time jobs to do: Peppercorn Creative and Acting. So it’s been a bit nuts. But it’s all coming to a head soon. Thank god. LOL…

      I hope you have a glorious sunny weekend in Montreal!! xo!

    Ok superstar, I’ve never been really big on blogs that show picture after picture of the same recipe, but each and every picture on this made me hungrier. So what I’m saying is: 1) awwwwwwwwwesome photography, and 2) I NEED THAT PIZZA.
